Need Direction: Is it worth to work in Core Java ???

I have recently joined a orgainization as a Java Engineer Trainee(0 Years of Experience) and working on a project(80% ABAP people are working on project)
in mainteance from last 2-3 Years.

The Work in the project is of basically in ABAP and Core Java (Only Basic Java code is being used related to JCO and XML) is only being used as
in interface for the data sharing between ABAP and Abrotext Editor(XML Editor).

But Most of the opening in Java for Experienced is in Struts/Hiberate/EJB and other frameworks
and J2EE. :-O

Please help and give me direction is it worth to work in Core Java with XML and gain experience in that. :-/

Should I study J2EE side by Side even it is not being used in project ??? :?:
